  • the network monitor looks at current performance key performance indicators (KPIs), such as reference signal receive power (RSRP), signal to interference/noise ratio (SINR), latencyjitter, packet loss, etc.
  • KPIs current performance key performance indicators
  • the current performance information provides the network monitor with information for how the network is currently performing, e.g., the current health of the network.
  • the network monitor uses a rolling average of KPI data to access the performance, e.g., health, of the network over time. The use of the rolling average KPI data to assess the network performance is valuable to reduce the risk of overreaction to temporary interruptions or outages within the network when evaluating the overall performance of the network.
  • sites also called base stations
  • These sites expand the coverage of the network based on a coverage area of the equipment at the site.
  • the coverage area of new site overlaps with a coverage area of one or more previously existing sites.
  • performance in the overlapping coverage areas of sites means that the performance within those overlapping coverage area is significantly changed. For example, one of ordinary skill in the art would expect an outer periphery of a coverage area for a previously existing site to have weaker performance in comparison with a location closer to a center of the coverage area of the site.
  • this description includes a method and a system for correcting the data in overlapping coverage areas for newly activated sites. This correction helps the network monitor to more precisely determine the performance of the network once the new site is activated. The ability to determine the performance of the network more precisely with the newly activated site helps to reduce the risk of sending maintenance/repair crews to sites that impact the overlapping coverage area. Additionally, the network monitor does not expend time and money attempting to diagnose a problem with sites that impact the overlapping coverage area based on outdated KPI data.
  • the method and system exclude data prior to the activation of the new site from the rolling average data for the overlapping coverage area from the information viewed by the network monitor. For example, in a situation where a new site is activated and the new site has a coverage area that overlaps with a preexisting coverage area in five map grids for the network, the method and system will exclude KPI data from the rolling average KPI data for those five map grids if the KPI data was collected prior to the activation of the new site.
  • a map grid is a geographic area usable to help network monitors determine to correlate network performance with specific locations covered by the network.
  • the rolling average KPI data viewed by the network monitor is more reflective of the actual performance of the network because poor performance at the periphery of the pre-existing coverage area is not skewing the rolling average KPI data based on an outdated network configuration.
  • the more precise and accurate the rolling average KPI data relied upon by the network monitors helps to invest maintenance/repair and expansion resources for the network more efficiently in order to more effectively maintain or enhance customer satisfaction for users of the network.

  • a minimum distance between existing sites is determined.
  • the minimum distance between existing sites is determined based on longitude and latitude locations of existing sites and neighboring existing sites. A radius of the Earth is also factored into the distance between existing sites. Once the distance between each existing site and neighboring existing sites within the network are determined, a standard deviation of the distances is used to determine the minimum distance between existing sites.
  • the existing sites are filtered based on the determined minimum distance to determine a final distance. Filtering the existing sites includes excluding sites that are a predetermined distance away from the new site for later determination of a coverage area of the new site. The final distance is subsequently used to determine a coverage area for the new site.

Further, in some embodiments, a proximity of existing sites depends on population density.
  • the predetermined distance is set based on a population density near the new site. In some embodiments, the predetermined distance is 50 kilometers (km) or less for a suburban or rural area. In some embodiments, the predetermined distance is 10 km or less for an urban area. In some embodiments, instead of a set magnitude, such as 50 km or 10 km, the predetermined distance is set as a multiplying factor of the standard deviation determined in operation 230. As a population density increases, the multiplying factor increases in order to help establish a precise and accurate determination of network performance.

  • the coverage area is determined based on the final distance determined in operation 235, as well as a location of the new site.
  • the location of the new site is determined based on longitude and latitude of the site as a center point of the coverage area.
  • a size of the coverage around surrounding the location of the new site is determined based on the final distance.
  • a multiplying factor is associated with the final distance to determine the size of the coverage area for the new site.

  • the multiplying factor ranges from about 0.5 to about 0.8. In some embodiments, the multiplying factor is about 0.7. In some embodiments, the multiplying factor is determined based on a magnitude of the final distance. For example, in some embodiments, as the final distance increases, the multiplying factor also increases. The final distance is determined based on geographic separation between sites. Therefore, as the distance between sites increases the impact of the activation of the new site will increase for a larger portion of the coverage area of the neighboring existing sites.
  • the network monitor is able to select an appropriate multiplying factor.

For example, in some embodiments where the rolling average has a duration of seven days, the removed KPI values are stored for seven days from the activation of the new site. At the end of the storing duration, the overwriting of the removed KPI values is permitted. Ensuring that the KPI values are stored for the duration of the rolling average following activation of the new site helps to provide reliable evaluation of the existing sites. Permitting overwriting of the KPI values following the duration of the rolling average after activation of the new site helps to reduce an amount of storage utilized by a system implementing the method 200.

Abstract

Un procédé de surveillance d'un réseau de télécommunication consiste à déterminer si une limite de couverture d'un nouveau site chevauche une zone de couverture d'un premier site existant. Le procédé consiste en outre à déterminer une distance minimale entre des sites existants parmi une pluralité de sites existants, en réponse à la détermination du fait que la limite de couverture chevauche la zone de couverture du premier site existant. Le procédé consiste en outre à déterminer une distance finale sur la base de la distance minimale. Le procédé consiste en outre à définir une zone de couverture pour le nouveau site sur la base de la distance finale. Le procédé consiste en outre à générer une interface utilisateur (UI) sur la base de valeurs de performance de réseau dans la zone de couverture pour le nouveau site et la zone de couverture du premier site existant, la génération de l'UI comprenant l'exclusion de valeurs de performance de réseau, associées au premier site existant, d'emplacements situés à l'intérieur de la zone de couverture du nouveau site.
